IMPROVEMENT IN HINGES.

Specification forming part of Letters Patent No. 210,686, dated December10, 1878; application filed March 19, 1878.

To all whom it may concern:

Be it known that I, HENRY E. GRIFFIN, of Olympia, in the county ofThurston and Territory of Washington, have invented a new and ImprovedDoor-Hinge, of which the following is a specification:

In the accompanying drawing, Figure 1 represents a horizontal section ofdoor with my improved hinge; and Fig. 2, a side elevation of the hinge,shown as attached to door and easin g.

Similar letters of reference indicate corresponding parts.

The invention relates to an improved doorhinge that may be put on at asaving of screws without difficulty even by inexperienced hands, forming a cheap, neat, and strong support for the door.

The invention consists of hinge sections or knuckles having legsextending at suitable inclination into the door and easing, the legshaving marking end spurs, and being securely attached byfastening-screwspassing through end of door and casin g and through holes of the legs.

In the drawing, A represents the knuckles or connecting-sections of myimproved hinge for hanging doors of all kinds. The knuckles A bearagainst the door and casing, and are cast with two or more legs, 13,that extend at a suitable angle of inclination from the face part of theknuckles, to be inserted into boreholes of the door or casin g that areset at an angle corresponding exactly to that of the legs. The angle ofthe bore-holes is readily obtained by suitable gage devices, the pointwhere the bit should be started being marked oii' by spurs a at the endsof the legs.

Each leg B is provided with one or more cross-holes, b, according to itslength, for the passage of the fastening-screws O, that are screwed inat points set off by dividers at the proper distance at the end of doorand side of decreasing, as shown in Fig. 1 of the drawing.

For light doors two screws only for each hinge-section are required,which forms a considerable saving in screws, as compared with the commondoor-hinges in use. The hinge requires less material, as the wings orplates are dispensed with, the lugs taking their place.

The hinges are readily applied to door and casin g. WVhen the door iswedged up to suitable height from the bottom to clear the same, twoholes are then bored by the auger-bit into the door and two in thecasing, and the hinge-sections inserted. The door will then readilyswing on the hinges, so that it can be opened and the fastening-screwsbe put in.

The hinge is of neat and ornamental appearance, as the wing-plates aredone away with, and thereby only the knuckles shown.

The legs may be made of any length and thickness, according to the sizeand thickness of doors, the hinge serving, when being shut tightly, tomark for the borings of the legs, so as to facilitate the applying ofthe same and hanging of the doors.

Having thus described myinventicn, I claim as new and desire to secureby Letters Patcut- 1. An im proved door-hinge made of knucklesectionswith inclined legs, secured to holes of the door and casing byfastening-screws, substantially as set forth.

2. The fastening-legs of the hinge-sections, having central end spurs tomark the place for boring holes for the legs, substantially asspecified.
